For completeness, I am adding an answer on how to install and use a non-English language with Tesseract OCR on Linux. Since this is the first result I got on Google and I think it may help someone.

To install German language on Ubuntu/Debian:

$ sudo apt-get install tesseract-ocr-deu

Language codes of all supported languages can be found here:

https://github.com/tesseract-ocr/tessdoc/blob/master/Data-Files-in-different-versions.md

To specify the language in OCR engine use option: -l lang, e.g. for German:

$ tesseract -l deu 'imagename' 'stdout'

You download them from tesseract repository.

At the moment tessdata for 4.0 is available here and tessdata for 3.04 here.

Solution 5:^[5]

I had to install Italian language but tesseract-lang installation cost 164 files, 654.0MB and gives the less precise version fast vs best so I decided to go manual

Add path to shell (if you brew on Mac find your path with brew info tesseract)

export TESSDATA_PREFIX=/usr/local/Cellar/tesseract/5.1.0/share/tessdata/

Update profile (if you are on zsh)

source ~/.zshrc

Save the language in my case the best version of ita

wget -O $TESSDATA_PREFIX/ita.traineddata https://github.com/tesseract-ocr/tessdata/raw/main/ita.traineddata

Now you should see the added language

tesseract --list-langs
